Abstract

PROBLEM TO BE SOLVED: To decrease resistance to movement of an upper rail 2 when the upper rail is unlocked Q from a lower rail 1, allow smooth movement of the upper rail 2, and prevent rattling of the upper rail 2 with respect to the lower rail 1 when the upper rail is locked P, even if there is an error in dimensional accuracy between the lower rail and the upper rail.SOLUTION: A seat slide device is switchable between: a locked state P in which a lock member 18 on the upper rail 2 side is engaged with/disengaged from lock holes 10 on the lower rail 1 side to restrict movement of the upper rail 2 with respect to the lower rail 1; and an unlocked state Q that permits movement thereof. In the unlocked state Q, a gap is formed in the vertical direction Z between a movable portion 29 and a guide section on the lower rail 1 side in a separated state SQ. In the locked state P, the movable portion 29 is in a close state SP and comes in contact with the guide section on the lower rail 1 side to eliminate the gap.

Description

本発明は、車両のシートスライド装置において、ロアレールに対しアッパレールを移動可能に支持する構造に関するものである。   The present invention relates to a structure for movably supporting an upper rail with respect to a lower rail in a vehicle seat slide device.

従来、下記特許文献１では、アッパレールに取り付けられたスライダの樹脂製突起がロアレールに対し弾性的に圧接されながらアッパレールが移動するため、その移動時にロアレールに対するアッパレールのがた付きを規制することができる。   Conventionally, in Patent Document 1 below, since the upper rail moves while the resin protrusion of the slider attached to the upper rail is elastically pressed against the lower rail, rattling of the upper rail with respect to the lower rail can be restricted during the movement. .

特開平１０−３１５８１０号公報Japanese Patent Laid-Open No. 10-315810

しかし、上記特許文献１では、スライダの樹脂製突起がロアレールに対し所定の弾力で常に圧接されるため、ロアレールに対するアッパレールのロック解除状態でロアレールに対するアッパレールの移動抵抗が生じ易くなるばかりではなく、ロアレールとアッパレールとの間の精度誤差によりその弾力が変化し、その移動抵抗が設定よりも大きくなり過ぎてアッパレールの移動操作に支障を来たすおそれがあった。また、ロアレールに対するアッパレールのロック状態では、ロアレールとアッパレールとの間の精度誤差によりスライダの樹脂製突起がロアレールに対し接離してロアレールに対するアッパレールのがた付きが生じるおそれがあった。   However, in the above-mentioned Patent Document 1, since the resin protrusion of the slider is always pressed against the lower rail with a predetermined elasticity, not only does the upper rail move with respect to the lower rail in the unlocked state, but also the lower rail does not easily move. Due to the accuracy error between the upper rail and the upper rail, its elasticity changes, and its movement resistance becomes too large than the set value, which may hinder the movement operation of the upper rail. Further, in the locked state of the upper rail with respect to the lower rail, there is a possibility that the resin protrusion of the slider comes in contact with and separates from the lower rail due to an accuracy error between the lower rail and the upper rail, causing the upper rail to rattle.

この発明は、シートスライド装置において、ロック解除状態でロアレールに対するアッパレールの移動抵抗を生じにくくするとともに、ロアレールとアッパレールとの間に精度誤差があってもロック状態でロアレールに対するアッパレールのがた付きを規制することを目的としている。   In the seat slide device, in the unlocked state, the resistance of the upper rail to the lower rail is less likely to be generated, and even if there is an accuracy error between the lower rail and the upper rail, the rattling of the upper rail to the lower rail is restricted in the locked state. The purpose is to do.

図１（ａ）（ｂ）に示すアッパレール２は、前端部２ａと後端部２ｂとの間で前後方向Ｘへ延設され、図３（ａ）（ｂ）及び図４（ａ）（ｂ）に示すように左右方向Ｙで互いに重合された一対の側板１１を有している。左右両側板１１の下部は、ロアレール１の収容室７に嵌め込まれ、収容室７の開口８に挿入されて左右方向Ｙで互いに摺動溝１２をあけて並ぶ左右両案内板部１３と、左右両案内板部１３の下端部から左右方向Ｙの外側上方へ屈曲されて収容室７の左右両溝９に挿入された腕板部１４とを有している。左右両腕板部１４にはロアレール１の底板部３に載置されたローラ１５が支持されている。左右両腕板部１４における前後方向Ｘの両端部には、図５（ａ）（ｂ）及び図６（ａ）（ｂ）に示すように前後方向Ｘへ延びるガイド１６が形成されている。各ガイド１６上には前後方向Ｘの外側へ向うに従い上方へ傾斜する規制面１６ａが形成されている。両側板１１の上部はロアレール１の開口８から上方へ突出している。   The upper rail 2 shown in FIGS. 1 (a) and 1 (b) extends in the front-rear direction X between the front end 2a and the rear end 2b, and FIGS. 3 (a) (b) and 4 (a) (b) ), A pair of side plates 11 superposed with each other in the left-right direction Y are provided. The lower portions of the left and right side plates 11 are inserted into the accommodation chamber 7 of the lower rail 1 and inserted into the opening 8 of the accommodation chamber 7 so that the left and right guide plate portions 13 are lined up with the sliding grooves 12 in the left-right direction Y. The arm plate portion 14 is bent from the lower end portions of both guide plate portions 13 to the outside in the left-right direction Y and inserted into the left and right grooves 9 of the storage chamber 7. The left and right arm plate portions 14 support rollers 15 placed on the bottom plate portion 3 of the lower rail 1. Guides 16 extending in the front-rear direction X are formed at both ends in the front-rear direction X of the left and right arm plate parts 14 as shown in FIGS. 5 (a), 5 (b) and 6 (a) (b). On each guide 16, a regulating surface 16 a that is inclined upward as it goes outward in the front-rear direction X is formed. The upper portions of the side plates 11 protrude upward from the opening 8 of the lower rail 1.

アッパレール２における前後方向Ｘの中央部で一方の側板１１に取着されたブラケット１７には、複数のロック爪１８ａ（ロック部）を有するロック部材１８が前後方向Ｘへ延びる支軸１９により上下方向Ｚへ回動可能に支持されている。ロック部材１８にはハンドル２０が連結されている。アッパレール２とロック部材１８との間には引張コイルばね２１が引掛けられている。一方の案内板部１３及び腕板部１４にはロアレール１の口板部６の各ロック孔１０に対応して複数の回避孔１３ａ，１４ａが形成されている。   A locking member 18 having a plurality of locking claws 18a (locking portions) is mounted on a bracket 17 attached to one side plate 11 at a central portion of the upper rail 2 in the front-rear direction X by a support shaft 19 extending in the front-rear direction X.

A plurality of avoidance holes 13 a and 14 a are formed in one guide plate portion 13 and arm plate portion 14 corresponding to each lock hole 10 of the mouth plate portion 6 of the lower rail 1.

図１（ａ）（ｂ）及び図３（ａ）に示すロック状態Ｐにおいて、ロック部材１８はハンドル２０とともに引張コイルばね２１により付勢されて支軸１９を中心に回動し、各ロック爪１８ａがロアレール１の一部のロック孔１０及びアッパレール２の各回避孔１３ａ，１４ａに係入されている。従って、ロック状態Ｐでは、ロアレール１に対しアッパレール２を前後方向Ｘへ移動させることができない。   In the locked state P shown in FIGS. 1 (a), 1 (b) and 3 (a), the lock member 18 is urged by the tension coil spring 21 together with the handle 20 and rotates about the support shaft 19 to each lock claw. 18 a is engaged with a part of the lock holes 10 of the lower rail 1 and the avoidance holes 13 a and 14 a of the upper rail 2. Therefore, in the locked state P, the upper rail 2 cannot be moved in the front-rear direction X with respect to the lower rail 1.

ロック状態Ｐからハンドル２０を引張コイルばね２１の弾性力に抗して押し下げると、図３（ｂ）に示すようにロック解除状態Ｑとなり、ロック部材１８が支軸１９を中心に回動して各ロック爪１８ａがロアレール１の一部のロック孔１０及びアッパレール２の各回避孔１３ａ，１４ａから離脱する。従って、ロック解除状態Ｑでは、ロアレール１に対しアッパレール２を前後方向Ｘへ移動させることができる。   When the handle 20 is pushed down against the elastic force of the tension coil spring 21 from the locked state P, the unlocked state Q is entered as shown in FIG. 3B, and the lock member 18 rotates about the support shaft 19. Each lock claw 18a is detached from a part of the lock holes 10 of the lower rail 1 and the avoidance holes 13a, 14a of the upper rail 2. Therefore, in the unlocked state Q, the upper rail 2 can be moved in the front-rear direction X with respect to the lower rail 1.

図２（ａ）（ｂ）に示すように、アッパレール２において、ロック部材１８に対する前後方向Ｘの両側にはそれぞれレバー２２（連動手段）が左右方向Ｙへ延びる支軸２３により回動可能に支持されている。レバー２２は、支軸２３の上方へ延びる上腕部２４と、支軸２３の下方へ延びる下腕部２５とを有している。上腕部２４にはロック部材１８と係合してロック部材１８の回動をレバー２２の回動として伝える伝動部２４ａが形成されている。左右両案内板部１３間の摺動溝１２にはスライダ２６（連動手段）がアッパレール２の移動方向（前後方向Ｘ）に沿ってアッパレール２に対し往復移動し得るように挿入されている。スライダ２６の基端部はレバー２２の下腕部２５に対し支軸２７により連結されている。左右両レバー２２の上腕部２４間には引張コイルばね２８が連結されている。スライダ２６における前後方向Ｘの端部に設けられた可動部２９は摺動溝１２から外側へ突出している。図１（ｂ）に示すように、可動部２９は、樹脂により成形され、中間部３０と、中間部３０から左右方向Ｙへ突出する当接部３１とを有している。図５（ｂ）及び図６（ｂ）に示すように、中間部３０と左右両当接部３１との間には通路３２が形成され、ロアレール１の口板部６が通路３２を通る。当接部３１にはガイド１６（連動手段）が挿通される規制孔３３が前後方向Ｘへ貫設されている。当接部３１にはロアレール１の左右両側板部４の内側の案内部４ａに面する壁部３４の内側に上下方向Ｚへ開放された空隙３１ａが形成されている。   2 (a) and 2 (b), in the upper rail 2, on both sides of the locking member 18 in the front-rear direction X, levers 22 (interlocking means) are rotatably supported by support shafts 23 extending in the left-right direction Y, respectively. Has been. The lever 22 includes an upper arm portion 24 that extends upward from the support shaft 23 and a lower arm portion 25 that extends downward from the support shaft 23. The upper arm portion 24 is formed with a transmission portion 24 a that engages with the lock member 18 and transmits the rotation of the lock member 18 as the rotation of the lever 22. A slider 26 (interlocking means) is inserted into the sliding groove 12 between the left and right guide plate portions 13 so as to reciprocate with respect to the upper rail 2 along the movement direction (front-rear direction X) of the upper rail 2. The base end portion of the slider 26 is connected to the lower arm portion 25 of the lever 22 by a support shaft 27. A tension coil spring 28 is connected between the upper arm portions 24 of the left and right levers 22. A movable portion 29 provided at an end portion of the slider 26 in the front-rear direction X protrudes outward from the sliding groove 12. As shown in FIG. 1B, the movable portion 29 is formed of resin and has an intermediate portion 30 and a contact portion 31 that protrudes from the intermediate portion 30 in the left-right direction Y. As shown in FIGS. 5B and 6B, a passage 32 is formed between the intermediate portion 30 and the left and right contact portions 31, and the mouth plate portion 6 of the lower rail 1 passes through the passage 32. A restriction hole 33 through which the guide 16 (interlocking means) is inserted is provided in the contact portion 31 in the front-rear direction X. In the abutting portion 31, a gap 31 a opened in the vertical direction Z is formed inside the wall portion 34 facing the guide portion 4 a inside the left and right side plate portions 4 of the lower rail 1.

さて、前述したロック部材１８のロック状態Ｐでは、図２（ａ）に示すように、左右両レバー２２の伝動部２４ａがロック部材１８から離れ、左右両レバー２２間の引張コイルばね２８の弾性力により左右両レバー２２が支軸２３を中心に回動して左右両スライダ２６を介して可動部２９が摺動溝１２の外側へ突出する。そのため、図４（ａ）及び図５（ａ）に示すように、可動部２９の当接部３１の規制孔３３がガイド１６の規制面１６ａにより上方へ押され、当接部３１がロアレール１の左右両上板部５の内側の案内部５ａに対しそれらの間の隙間Ｇをなくすように当接する接近状態ＳＰとなる。従って、可動部２９の当接部３１はロック状態Ｐで案内部５ａに対し圧接される。   Now, in the locked state P of the lock member 18 described above, the transmission portion 24a of the left and right levers 22 is separated from the lock member 18 and the elasticity of the tension coil spring 28 between the left and right levers 22 is shown in FIG. The left and right levers 22 rotate about the support shaft 23 by force, and the movable portion 29 protrudes outside the sliding groove 12 via the left and right sliders 26. Therefore, as shown in FIGS. 4A and 5A, the restriction hole 33 of the contact portion 31 of the movable portion 29 is pushed upward by the restriction surface 16 a of the guide 16, and the contact portion 31 becomes lower rail 1. It will be in the approach state SP which contact | abuts so that the clearance gap G between them may be eliminated with respect to the guide part 5a inside the right-and-left both upper board part 5. FIG. Therefore, the contact portion 31 of the movable portion 29 is pressed against the guide portion 5a in the locked state P.

また、前述したロック部材１８のロック解除状態Ｑでは、図２（ｂ）に示すように、左右両レバー２２の伝動部２４ａがロック部材１８により引張コイルばね２８の弾性力に抗して上方へ押され、左右両レバー２２が支軸２３を中心に回動して左右両スライダ２６を介して可動部２９が内側へ没入する。そのため、可動部２９の左右両当接部３１の規制孔３３に対するガイド１６の規制面１６ａの規制が解除されて可動部２９が下動し、ロアレール１の左右両上板部５の内側の案内部５ａに対しそれらの間で隙間Ｇを生じるように上下方向Ｚで離間する離間状態ＳＱとなる。従って、ロック解除状態Ｑで、可動部２９の当接部３１がロアレール１側の案内部４ａに軽く接触するとともにロアレール１側の案内部５ａから上下方向Ｚで離間した状態で、ロアレール１に対しアッパレール２を前後方向Ｘへ移動させることができる。   Further, in the unlocked state Q of the lock member 18 described above, as shown in FIG. 2B, the transmission portions 24 a of the left and right levers 22 are moved upward against the elastic force of the tension coil spring 28 by the lock member 18. The left and right levers 22 are rotated around the support shaft 23 and the movable portion 29 is immersed inward via the left and right sliders 26. Therefore, the restriction of the restriction surface 16a of the guide 16 with respect to the restriction holes 33 of the left and right abutting parts 31 of the movable part 29 is released, the movable part 29 moves down, and guides inside the left and right upper plate parts 5 of the lower rail 1 It will be in the separation state SQ which leaves | separates in the up-down direction Z so that the clearance gap G may be produced between them with respect to the part 5a. Accordingly, in the unlocked state Q, the abutting portion 31 of the movable portion 29 makes a slight contact with the guide portion 4a on the lower rail 1 side and is spaced from the guide portion 5a on the lower rail 1 side in the vertical direction Z with respect to the lower rail 1. The upper rail 2 can be moved in the front-rear direction X.

次に、本発明の第２実施形態にかかるシートスライド装置について第１実施形態との相違点を中心に図７〜８を参照して説明する。なお、第１実施形態の図５（ａ）（ｂ）及び図６（ａ）（ｂ）はそれぞれ第２実施形態の図７（ａ）（ｂ）及び図８（ａ）（ｂ）に対応する。   Next, a seat slide device according to a second embodiment of the present invention will be described with reference to FIGS. 7 to 8 with a focus on differences from the first embodiment. 5A, 5B and 6A, 6B of the first embodiment correspond to FIGS. 7A, 7B, 8A, and 8B of the second embodiment, respectively. To do.

前後方向Ｘへ延びる左右両ガイド１６において、第１実施形態と同様にロアレール１の上板部５の内側の案内部５ａに面する規制面１６ａが前後方向Ｘの外側へ向うに従い上方へ傾斜するばかりでなく、ロアレール１の側板部４の内側の案内部４ａに面する規制面１６ｂが前後方向Ｘの外側へ向うに従い互いに広がるように傾斜している。当接部３１は左右方向Ｙへ若干撓み得る。   In the left and right guides 16 extending in the front-rear direction X, the regulation surface 16a facing the guide part 5a on the inner side of the upper plate part 5 of the lower rail 1 is inclined upward as it goes outward in the front-rear direction X, as in the first embodiment. In addition, the regulating surface 16b facing the guide portion 4a on the inner side of the side plate portion 4 of the lower rail 1 is inclined so as to spread toward the outside in the front-rear direction X. The contact part 31 can be bent slightly in the left-right direction Y.

前述したロック部材１８のロック状態Ｐでは、第１実施形態と同様に当接部３１がロアレール１の左右両上板部５の内側の案内部５ａに対しそれらの間の隙間Ｇをなくすように当接するとともに、ロアレール１の左右両側板部４の内側の案内部４ａに対しそれらの間の隙間Ｇをなくすように当接する接近状態ＳＰとなる。従って、可動部２９の当接部３１はロック状態Ｐで案内部５ａ，４ａに対し圧接される。   In the lock state P of the lock member 18 described above, the contact portion 31 eliminates the gap G between the guide portions 5a inside the left and right upper plate portions 5 of the lower rail 1 as in the first embodiment. The contact state SP is brought into contact with the guide portions 4a inside the left and right side plate portions 4 of the lower rail 1 so as to eliminate the gap G therebetween. Accordingly, the contact portion 31 of the movable portion 29 is pressed against the guide portions 5a and 4a in the locked state P.

また、前述したロック部材１８のロック解除状態Ｑでは、第１実施形態と同様に当接部３１がロアレール１の左右両上板部５の内側の案内部５ａに対しそれらの間で隙間Ｇを生じるように上下方向Ｚで離間するとともに、ロアレール１の左右両側板部４の内側の案内部４ａに対しそれらの間の隙間Ｇを生じるように左右方向Ｙで離間する離間状態ＳＱとなる。従って、ロック解除状態Ｑで、可動部２９の当接部３１がロアレール１側の案内部５ａ，４ａから上下方向Ｚ及び左右方向Ｙで同時に離間した状態で、ロアレール１に対しアッパレール２を前後方向Ｘへ移動させることができる。   Further, in the unlocked state Q of the lock member 18 described above, the contact portion 31 forms a gap G between the guide portions 5a inside the left and right upper plate portions 5 of the lower rail 1 in the same manner as in the first embodiment. In this state, the separation state SQ is separated in the left-right direction Z so that a gap G is generated between the guide portions 4a inside the left and right side plate portions 4 of the lower rail 1 and the gaps G therebetween. Accordingly, in the unlocked state Q, the upper rail 2 is moved in the front-rear direction with respect to the lower rail 1 in a state where the abutting portion 31 of the movable portion 29 is simultaneously separated from the guide portions 5a, 4a on the lower rail 1 side in the vertical direction Z and the horizontal direction Y. Can be moved to X.

本実施形態は下記の効果を有する。
（１） ロック部材１８のロック解除状態Ｑで前後両可動部２９が連動手段を介して離間状態ＳＱを取ってロアレール１側の案内部５ａに対し上下方向Ｚで隙間Ｇを生じるため、ロアレール１とアッパレール２との間に精度誤差があっても、ロアレール１に対するアッパレール２の移動抵抗が生じにくくなって、アッパレール２を円滑に移動させることができる。 This embodiment has the following effects.
(1) In the unlocked state Q of the lock member 18, both the front and rear movable parts 29 take the separated state SQ via the interlocking means, and a gap G is generated in the vertical direction Z with respect to the guide part 5a on the lower rail 1 side. Even if there is an accuracy error between the upper rail 2 and the upper rail 2, movement resistance of the upper rail 2 with respect to the lower rail 1 is less likely to occur, and the upper rail 2 can be moved smoothly.

（２） ロック部材１８のロック状態Ｐで前後両可動部２９が連動手段を介して接近状態ＳＰを取ってロアレール１側の案内部５ａに対しそれらの間の隙間Ｇをなくすように当接するため、ロアレール１とアッパレール２との間に精度誤差があっても、ロアレール１に対するアッパレール２のがた付きを規制することができる。   (2) When the locking member 18 is in the locked state P, both the front and rear movable parts 29 take the approaching state SP via the interlocking means and come into contact with the guide part 5a on the lower rail 1 side so as to eliminate the gap G between them. Even if there is an accuracy error between the lower rail 1 and the upper rail 2, rattling of the upper rail 2 with respect to the lower rail 1 can be restricted.

（３） 簡単な連動手段（アッパレール２側におけるレバー２２やスライダ２６やガイド１６）により、ロック部材１８のロック解除状態Ｑやロック状態Ｐに応じて可動部２９を離間状態ＳＱや接近状態ＳＰに容易に設定することができる。   (3) By simple interlocking means (the lever 22, slider 26, and guide 16 on the upper rail 2 side), the movable portion 29 is moved to the separated state SQ or the approached state SP according to the unlocked state Q or the locked state P of the lock member 18. It can be set easily.

（４） アッパレール２に対する前後方向Ｘの両側と左右方向Ｙの両側とでそれぞれ、ロアレール１側の案内部５ａに対しアッパレール２側の可動部２９を接離するので、ロック解除状態Ｑにおけるアッパレール２の移動抵抗や、ロック状態Ｐにおけるアッパレール２のがた付きをバランス良く解消することができる。   (4) Since the movable portion 29 on the upper rail 2 side contacts and separates from the guide portion 5a on the lower rail 1 side on both sides in the front-rear direction X and both sides in the left-right direction Y with respect to the upper rail 2, the upper rail 2 in the unlocked state Q And the backlash of the upper rail 2 in the locked state P can be eliminated with a good balance.
